In testing, I found that there were some problems using Postgres in a
situation where you start the app, connect to the database, get some
data, fork, reconnect, and and then get more data. I suspect that
this has more to do with the DBD::Pg driver and/or Postgres itself
than Alzabo. I don't believe this would be a problem with an app
which forks before ever connecting to the database (such as mod_perl).
